Title: Driver for ic tester
Inventor: SEKINO TAKASHI
IPC: G01R31/28
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To improve the operability of the ON resistance regulation of a photoconductive switch by reducing dissipation power and decreasing the leakage current at the time of high output impedance of a driver. SOLUTION: Only one main constant-current source 8 and bias constant current source 11 are adopted. The respective current sources are selectively connected to laser diodes LDi by a driver output voltage selector 21 and bias switching circuit 22. A low leakage current mode is provided separately from a normal high speed mode, the bias currents of LDi at the time of high output impedance of a drive are all set to zero to suppress the leakage current of a PCSW. The LDi at the time of ON of the PCSWi is driven only by the main current Iai, and no bias current flows. Accordingly, the ON resistance Roni of the PCSW can be regulated in a short time by variably setting distribution ratio of the main current distributor ADi.

Title: Split operation control type internal combustion engine
Inventor: UENO MAKOTO
IPC: F02D21/08
Filed: 1981-05-02
Abstract: PURPOSE:To prevent the pumping loss and the abrupt variation of the output torque, by holding the suction stopper valve at the full-open, semi-open and the full-close while the E.G.R.  valve at the full-open and the full-close when the operation of an engine which performs the split operation in accordance to the load will transfer from the light load to the heavy load  or from the heavy load to the light load. CONSTITUTION:When an engine will transfer from the light load to the heavy load operation,  the solenoid of an exchange valve 45 is actuated to conduct the negative pressure chamber 34  to the atmosphere, thereby a diaphragm 32 is moved to semi-open the suction stopper valve  26. When said valve 26 is held temporalily at the semi-open position, an exchange switch 29  will contact with a fixed contact 51 and an electromagnetic exchange valve 59 is actuated by the connection signal. Since the negative pressure chamber 56 of the E.G.R. valve 54 will conduct to the atmosphere, when the diaphragm 55 will move and the valve body 61 will fully  close the E.G.R. path 53, the switch 63 is connected to the contact 65. Consequently the electromagnetic exchange valve 43 is actuated by the connection signal and the fuel injection  valve 17a will start the injection. When the exchange valve 43 is actuated the negative pressure chamber 33 will by conducted to the atmosphere thereby the diaphragm 31 will move  gradually to the negative pressure chamber 34 thus to fully open the suction stopper valve 26.

Title: Formation of honeycomb body
Inventor: ISHIKAWA YASUSHI
IPC: B01D53/86
Filed: 1995-03-24
Abstract: PURPOSE: To obtain a metal carrier without defective joining even when the thickness of a foil is lessened by bringing an electrode into contact with a flat foil on the outer peripheral surface of a honeycomb body that is being formed and partially resistance-welding the flat foil and a corrugated foil. CONSTITUTION: In a method where a flat foil 2 and a corrugated foil in which the flat foil 2 is corrugated to form are wound about a take-up axis 4 to form a honeycomb body 1, an electrode 5 is brought into contact with the flat foil 2 on the outer peripheral surface of the honeycomb body 1 that is being formed, and the flat foil 2 and the corrugated foil 3 are partially resistance-welded. In this way, since the contact surface pressure of the flat foil 2 and the corrugated foil 3 is kept high from the central part of the honeycomb body 1 to the outer peripheral surface thereof, the problem of defective joining is solved. Particularly, a thin foil honeycomb body <40μm thick is stably produced. By adopting the thin foil honeycomb body, waste gas cleaning capacity is improved because the carrier is rapidly heated to a temperature at which a catalyst acts.

Inventor: SHIOBARA RYUZO
IPC: A47B13/00
Filed: 1995-03-27
Abstract: PURPOSE: To provide a standing device (for low table) having foldable legs in which a stand lock is automatically unlocked only by turning over the main body to a certain extent. CONSTITUTION: In a state where legs are upright and standing, a moving ball guiding passage 8 between a top plate side moving ball receiving port 6 on a lower side and a leg side moving ball receiving port 7 on an upper side is opened through delivery ports 6b and 7b of a moving ball. The moving ball 9 with a weight is stopped in the lower moving ball receiving port 6 on the top plate side which extends over a boundary face P and is in a locked state where the legs are prevented from being turned or folded as shown in figure (a). When the top plate is turned over until the tips of the legs are apart from the floor face in such a state, the levels of the receiving ports are turned over in which the top plate side moving ball receiving port 6 becomes high and the leg side moving ball receiving port 7 becomes low as shown in figure (b).  Consequently, since the weighted moving ball 9 moves from the top plate side moving ball receiving port 6 to the leg side moving ball receiving port 7 via the moving ball guiding passage 8 which is opened, the lock state of turning is automatically unlocked.

Abstract: PROBLEM TO BE SOLVED: To provide an image forming device control system, in which the number of notices caused by maldetection of abnormality is reduced, by comparing the difference between the time of a previous abnormality generation and the present time by a timing means and providing a notice if the difference is less than a certain time (an SC call interval), i.e., if abnormalities are continuously generated. SOLUTION: First, a difference is taken between a variable 'the time of the generation of a previous SC' stored in a nonvolatile RAM and 'present time' and the difference is inserted into a variable work (S41). Then, a comparison is made between the work and an 'SC call interval'. In the case of the work <= the 'SC call interval' (S42; Y), a 'continuous SC generation flag' is turned ON (S43). In the case of the work > 'SC call interval' (S42; N),the 'continuous SC generation flag' is turned OFF (S44). Then, the 'present time' is inserted into the 'previous SC generation time'.
